1. Deploy the openstack helm chart on Azure Managed Openshift Service


    To deploy the OpenStack Helm chart on Azure Managed OpenShift Service using Pulumi, you need to follow these general steps:

    1. Create an Azure Managed OpenShift cluster.
    2. Install Helm and configure it for your OpenShift cluster.
    3. Deploy the OpenStack Helm chart to the OpenShift cluster.

    Below is a Pulumi program in TypeScript that demonstrates how to deploy an Azure Managed OpenShift Service cluster and then use Helm to deploy the OpenStack Helm chart. Please note that deploying OpenStack via Helm on an OpenShift cluster is an advanced scenario and requires the OpenStack Helm charts to be fully compatible with OpenShift, as there are specific security and operational considerations with OpenShift.

    Before you begin, ensure that you have the Azure CLI installed, logged in, and configured with the correct subscription where the resources should be deployed. Also, ensure you have Helm CLI installed and that you have a valid OpenStack Helm chart ready for deployment.

    Let's break down the steps included in the Pulumi program:

    1. Instantiate an Azure Managed OpenShift cluster using the azure-native.containerservice.OpenShiftManagedCluster resource.

    2. Use the Pulumi kubernetes package to apply Helm charts. We'll use kubernetes.helm.v3.Chart resource which encapsulates deploying Helm charts.

    3. Provide configuration details for the OpenShift cluster, such as location, resource group, OpenShift version, and the agent pool profile that defines node type and count.

    4. Since connecting to and managing resources within an Azure Red Hat OpenShift cluster often requires specific setup regarding kubectl and helm, those steps are not included in the Pulumi program and should be done separately after the program runs.

    Now, let's write the Pulumi program:

    import * as pulumi from "@pulumi/pulumi"; import * as azureNative from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azureNative.resources.ResourceGroup("resourceGroup", { resourceGroupName: "openShiftResourceGroup", location: "East US", // Choose the appropriate Azure region }); // Create an Azure Managed OpenShift cluster const openShiftManagedCluster = new azureNative.containerservice.OpenShiftManagedCluster("openShiftCluster", { resourceName: "myOpenShiftCluster", resourceGroupName: resourceGroup.name, location: resourceGroup.location, openShiftVersion: "4.6", // Choose an appropriate OpenShift version networkProfile: { vnetCidr: "", }, masterPoolProfile: { count: 3, vmSize: "Standard_D4s_v3", }, agentPoolProfiles: [{ name: "agentpool", count: 3, vmSize: "Standard_D4s_v3", }], }); // After creating the OpenShift cluster, connect to it and configure Helm using the Azure CLI and Helm CLI. // Please follow Azure's documentation to set up kubectl context: https://docs.microsoft.com/en-us/azure/openshift/tutorial-create-cluster // Then, setup Helm if not already: https://helm.sh/docs/intro/install/ // Define the OpenStack Helm chart and deploy it const openStackHelmChart = new k8s.helm.v3.Chart("openStackHelmChart", { // You'll need to specify the correct chart name and repository details depending on where your OpenStack Helm chart is located. chart: "openstack", version: "latest", // Use the appropriate chart version fetchOpts: { repo: "http://my-chart-repo.local/", // Replace with the OpenStack Helm chart's repository URL }, // Make sure to provide all necessary values.yaml content through 'values' field or create a separate config file. values: { // ... specify your configuration (if required) ... }, }, { provider: openShiftManagedCluster }); // Provide the OpenShift cluster as the provider of this Helm chart // Export the cluster's name and kubeconfig export const clusterName = openShiftManagedCluster.resourceName; export const kubeconfig = openShiftManagedCluster.kubeconfig;

    This program sets up the Azure Red Hat OpenShift cluster and specifies a Helm chart deployment. Remember that after running this Pulumi program, you need to manually set up kubectl context and Helm CLI to interact with your OpenShift cluster and Helm, respectively.

    Please adjust the chart, version, fetchOpts, and values fields in the openStackHelmChart resource to match your actual OpenStack Helm chart details.

    Furthermore, since OpenStack is an extensive platform with various services and components, it's important to ensure that the specific Helm chart you use is tailored for deployment on OpenShift and that you have considered networking, storage, and computing resources accordingly.

    After the deployment is complete, you can export the necessary details like clusterName and kubeconfig to connect to your AKS cluster and verify the OpenStack deployment through the OpenShift web console or CLI.
